RAILING-BASE.

Specification of Letters Patent.

Patented May 6, 19119.

Application filed December 4, 1917. Serial No. 205,304.

To all whom it may concern Be it known that I, HENRY W. PLEIs'rER, a citizen of the United States, residing at IVestfield, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Railing-Bases, of which the following is a specification, taken in connection with the accompanying drawing.

My invention relates to an improved railing base for attaching pipe structures of any kind to floors, walls or ceilings built of brick, stone, terra cotta, concrete, or other similar material;

My improved railing base is more economical to install and makes a neater job than the railing bases now in use.

My invention further relates to certain details of construction which will be described in the specification and pointed out in the claims.

In the accompanying drawing I have shown different uses to which my railing base may be put, but it is of course to be understood that my invention is not to be confined to these particular uses, which are simply shown by Way of example.

In these drawings, the same reference numerals refer to similar parts.

Figure 1 is a perspective view of my ra ling base used in connection with a hand ra1l.

Fig. 2 is a perspective view of my railing base mounted in a support which is shown in section.

Fig. 3 is a side elevation of a detail.

Fig. 4 is a side elevation showing the railing base used as an overhead pipe support, the ceiling being shown in section.

In the illustrative embodiment of my in vention 1 is a railing base formed of radial movable gripping members and 3 and op erating cones 4 and 5. It 1s to be understood, however, that my invention is not to be confined to this particular form of gripping members. The cone 4 is provided with interior screw threads which cooperate with the screw threads upon the screw 6. This is a common construction in the art and shown for example in the patent to Boone 729124 August 26, 1903. Many other patents could also be referred to to show this old and well known construction. The cone 5 is unthreaded. I have shown in this particular form of my invention, the cones provided with arrow heads 7 and 8 which engage with corresponding inclined surfaces 9, 9 on the radially movable gripping members 2 and 3. Spring bands 10, 10 may also be used to keep the members together.

The screw 6 is fast to the cap 11. This cap is provided with a recessed portion 12 having female screw threads, and on its exterior is provided with a tool engaging surface 13.

By drilling only one hole 14: in the masonry or other support 15, my railing base can be secured by inserting the gripping portion in the hole li and then rotating the cap 11 by a monkey wrench, or other suitable tool cooperating with the hexagonal surface 13. This causes the cap 11 with its screw 6 to rotate which in turn forces the cone 4 between the members 2 and 3 and also causes the cone 5 to move to expand the members 2 and 3. One or two rotations of the cap will give a quick, positive and permanent grip between the members 2 and 3 and the surface of the hole 1 L. To the railing base so secured stanchions 16, 16 of the hand rail 17 maybe secured, Fig. 1. Or the hand rail may be secured directly in one of the railing bases mounted in the side of the edifice 18, rather than on one of the steps 19. It will. be noted that when the stanchions 16, or the hand rail 17, are screwed directly into the railing base not only is a strong and permanent fastening made, but a very pleasing and handsome eifect is produced.

I also preferably provide the inner ortion of my cap 11 with a cylindrical oss 20 which fits snugly in the hole lt and pre vents side motion and adds to the rigidity of the fastening.

Of course my railing base may be used to support various objects or work. In Fig. 4t I have shown an overhead pipe support 21 held to the ceiling 22 by means of one of my railing bases. They may be used for various other purposes such for example as supporting hitching posts lamp posts, standards for pilgrble partitions, racks, shelving and the Having thus described this invention in connection with an illustrative embodiment thereof, to the details of which I do not desire to be limited, what is claimed as new and what is desired to secure by Letters Patent is set forth in the appended claims.

1. The combination in a railing base of gripping members, a screw to operate said gripping members, and a recessed cap to operate said screw.

2. The combination in a railing base of gripping members, a screw to operate said gripping members, a recessed cap fast 011 said screw and provided with tool engaging surfaces to rotate the cap and also provided With interior concealed screwthreads to cooperate with and hold the article supported.

3. The combination in a railing base of gripping members, a screw to operate said gripping members, a recessed cap fast on said screw and provided with a cylindri- 1 cal exterior to fit in a hole in a support and with tool engaging surfaces to rotate the cap and also provided with interior concealed screWthreads to cooperate with and hold the articles supported.
